` junction with a refrigerator cabinet whereby a refrigerant-liquefying means is mounted in such a manner as to be positionable in either of two positions.

The invention contemplates and has for its principal object the provision of an improved refrigerating apparatus comprising a cabinet having means for supporting its bottom in spaced relation above the floor, the space at the bottom providing a machineryv space or compartment Within which is normally housed refrigerantliquefying machinery such as a motor-compressor unit and a condenser. The refrigerant-liquefying machinery is mounted so that it may be moved from a position in which it is `disposed normally within the confines of the machinery space or compartment to a position in which at least a part of the machinery extends outside the space or compartment. When the machinery is normally disposed within the confines of the compartment, the refrigerating apparatus is more easily transported and the machinery is more effectively protected against damage incident to transport. It is found, however, that the machinery operates at higher eiiciency when it is exposed at one side of the compartment or space, since normally the cabinet is placed against a wall and maximum circulation of air to cool the condenser is not obtained.

Other objects and features of the invention will be apparent to those skilled in the art upon an examination of the following detailed description and accompanying sheets of drawings of a preferred embodiment of the invention.

In the drawings, Figure l is a side elevation of a refrigerating apparatus embodying the principles of the invention.

Figure 2 is an end elevation of the same structure, the outward cr operating position of the refrigerant-liquefying machinery being indicated in dot-dash lines.

Figure 3 is a transverse sectional view taken on the line 3--3 of Figure 1.

Figure 4 is an enlarged sectional view showing in detail the construction of the means for mounting the machinery frame, the view being taken substantially along the line 4-4 of Figure 3.

Although the following description will pertain to a preferred embodiment of the invention as 3 Claims. (Cl. 6ft-11G) associated with a refrigerating apparatus of the the invention has wider application; the disclosure should be taken therefore as illustrative and not limiting.

The refrigerating unit has a. cabinet having opposed end walls II) and opposed side walls II, the structure forming a box or chest closed by a bottom wall I2, the intermediate portion of which is. arched (Figure 1). The cabinet may be closed in the usual manner as by a hinged cover I3.

The cabinet is supported with its bottom I2 in spaced relation above the floor, the supporting means comprising a base including longitudinally spaced supports in the form of end elements or legs I4. As best shown in Figure 3 each end element is preferably formed of sheet metal and of box-like construction, the outer walls of which are respectively in vertical alinement With the end walls I0 of the cabinet.

It will be noted that the bottom I2 of the cabinet and the end elements or legs I4 provide a space or compartment below the cabinet. This space serves to accommodate refrigerant-liquefying machinery generally indicated by the reference numeral I5. As is conventional, this machinery may include a motor-compressor I6 and a condenser I1. The suction side of the compressor is connected in the usual manner by tubing I8 to an evaporator (not shown), and the condenser I1 is connected to the compressor by means of tubing I9, this latter tubing being broken away in Figure 3 to illustrate more clearly supporting structure for the machinery. The machinery unit- I5 is of such size as to be confnable in the machinery space below the cabinet; that is to say, normally no part of the machinery projects beyond the side walls II of the cabinet.

Each end element or leg I4 is provided with bracket means comprising a pair of transversely spaced angle bars 20, the horizontal leg of each of which carries a vertical securing means in the form of a bolt 2 I. The machinery unit is carried on a supporting frame 22, which preferably comprises a plurality of longitudinally running angle bars 23 cross connected at their ends by a pair of transversely running angle bars 24. Each of the angle bars 24 is longitudinally slotted in two places at 25 to receive the proximate mounting bolts 2|. As shown in Figure 4, the bolts 2| may pass through rubber cushions 25 for resiliently mounting the frame 22 on the brackets 20. The supporting frame 22 is also of such size as to be cabinet.

In the operation of the reirigerating unit, the bolts 2| are loosened so that the frame 22 may be slid or moved horizontally outwardly through one open side of the machinery space. The machinery unit then occupies the position shown in Figure 3 and shown in dot-dash lines in Figure 2. In this position a portion of the machinery unit extends at one side of the cabinet beyond the proximate side wall l i. This position of the unit may be termed the operating position, for it is found that the unit operates at increased eiilciency in this position as compared to its operating eiciency when occupying its position entirely within the machinery space. This position of the machinery unit, of course, increases the overall width of the cabinet. However, when it is desired to transport the unit, the machinery carrying frame, together with the machinery thereon, may be moved inwardly so that it is conned within the machinery space. In this position of the parts utmost protection is afforded the machinery and the overall width of the cabinet is no greater than the transverse width of the end walls lll.

The bolts 2l may be completely removed in the event that it is desired to completely remove the frame 22 and the unit I5.

The foregoing ldescription is, of course, based amai/2 upon a preferred embodiment of the invention,

and it will be obvious that numerous modications and alterations may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims,

What is claimed is: n
